Digital wheel speed sensors detect the rotational speed of vehicle wheels and convert this data into electrical signals using magnetism and electromagnetic induction. These sensors typically include a Hall effect or magnetic sensor placed near a toothed wheel attached to the wheel. As the wheel rotates, the sensor detects changes in the magnetic field caused by the passing teeth. This information is sent as a digital signal to the vehicle's electronic control unit (ECU), which processes it for crucial applications like anti-lock braking, traction control, and stability control. Thus, digital wheel speed sensors provide accurate, real-time data vital for vehicle safety and performance.
